Businesses are sending more SMS messages to their customers than ever before. As SMS becomes a primary means of B2C communication, it is essential that these messages reach their desired destination securely.

Mobile Number Portability (MNP) lookups provide businesses with the resources they need to not only ensure that SMS messages get through to the right customer, but that B2C communication is as efficient as possible.

In this guide, we’ll walk you through what MNP lookup is and why it’s so important for businesses.

What is Mobile Number Portability lookup?

Mobile Number Portability, or MNP, allows individuals to change mobile networks without having to change their phone number. Of course, this streamlines the switching experience for customers but, at the same time, it also makes it harder for businesses to keep track of customers’ phone numbers as they move from one network to the next.

To combat this challenge, businesses started using MNP databases. Now, every time a phone number is ported to another service provider, that phone number's status is updated in the MNP database. This informs other networks as to where a phone number is being used.

MNP lookup is a service that checks this database to determine the status of a specific phone number. It can provide you with information such as the mobile network a number is currently associated with, whether that number is active, and what country the number is being used in.

Why is it important for businesses to have an up-to-date database for MNP lookup?

Telcos and businesses alike can use MNP information in several ways. A simple use case is A2P messaging, wherein businesses push out thousands of SMS messages automatically via software. By checking the MNP database before sending out aggregate messages, businesses can avoid sending messages to inactive numbers, making A2P campaigns a more cost-effective practice.

MNP also prevents businesses from sending sensitive information to a phone number that no longer belongs to its previous owner, like one-time passwords and other means of account validation.

In an age of PSD2, A2P, and sophisticated mobile fraud, having access to an up-to-date MNP database is crucial for businesses. MNP lookup gives companies a high level of certainty that the messages they're sending out are arriving to the right recipient.


What are the benefits of MNP lookup?

One of the key benefits of MNP lookup is that it reduces the risks and errors commonly associated with message delivery.

Beyond that, though, MNP can help businesses find the most direct routes for SMS messages. Not only does MNP tell businesses if a number is active, but also which mobile provider it's active with and in which country. Using this information allows routing software to find the best route possible to this number, delivering messages as quickly, securely, and cost-effectively as possible.
